Invading Trout Reduce Forest Spiders by Altering the Stream Food Web That Supplies Their Prey
A team of researchers from the U.S. and Japan have shown that exotic species can have strong effects that degrade not only the ecosystems they invade, but also spread to adjacent ecosystems as well. Colden Baxter, Kurt Fausch and Phillip Chapman from Colorado State University collaborated with Masashi Murakami of Hokkaido University to conduct a large experiment in a watershed of northern Japan. The study showed that non-native rainbow trout usurped forest insects that fell into the stream, depriving native trout of more than 80% of their diet. This forced the native fish to feed primarily on insect larvae that live on the stream bottom, which decreased adult insects emerging from the stream to the forest. In turn, this caused a 65% reduction in forest spiders that, like other forest-dwellers such as birds and bats, prey on insects emerging from the stream. This research demonstrates that species invasions can decouple critical connections between ecosystems like streams and forests and have strong effects that propagate across their boundaries to generate ecological surprises.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
